Audio Tag Classification
This task will compare various algorithms' abilities to associate descriptive tags with 10-second audio clips of songs. Two datasets are used to implemt a pair of sub tasks, based on the Mood and MajorMiner tag datasets. This task is very much related to the other audio classification tasks, however, multiple tags may be applied to each example rather than single classification.
Algorithms will be evaluated both on their ability to apply binary classifications of tags to examples, but also on their ability to rank tags for a track by sking them to return an affinity score for each tag/track pair.
Audio tag classification was first run at MIREX 2008 https://www.music-ir.org/mirex/2008/index.php/Audio_Tag_Classification and as a special MIREX task at 2009 https://www.music-ir.org/mirex/2010/index.php/SpecialTagatuneEvaluation .
